Pyro didn't have a problem going through with it. There was actually something very internally satisfying about it, as far as he was concerned. Of course, he liked fire to start with, and he didn't really like people, so setting people on fire perhaps made them more likable, as far as he's concerned. Either way, it didn't much matter just at the moment. Towards the end, he snorts just faintly, shaking his head. "I don't like the bad, so I usually don't take it. I just take the good and leave the bad for someone else."
He flashed another one of those grins as they got towards the upstairs, and gestured towards one of the halls of little apartment things. "I'm sweaty, and hot, and going to take a shower. So unless you're going to join me.." A raised eyebrow, and another cocky, boyish grin. Of course, how's he to know that it might kill him if she did.
